ATI Pharmacology Proctored Exam 2023 Quizlet
1. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
2. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?
- A. Use a blood pressure cuff to distend the veins.
- B. Select the antecubital area to insert the IV catheter.
- C. Distend the veins by using a blood pressure cuff.
- D. Direct the client to lower his arm below his heart.
Correct answer: C
Rationale: The correct answer is C. The healthcare professional should distend the veins using a blood pressure cuff to make the veins more visible and accessible for IV catheter insertion. This technique helps reduce the risk of overfilling the vein, which can lead to complications such as hematoma formation. Choices A, B, and D are incorrect because while selecting the antecubital area is often appropriate for IV insertion in adults, the key action in this scenario is to distend the veins using a blood pressure cuff to facilitate the procedure.
3. What instruction should the healthcare provider include to minimize an adverse effect of Clomipramine for OCD in an adolescent client?
- A. Wear sunglasses when outdoors.
- B. Check your temperature daily.
- C. Take this medication in the morning.
- D. Add extra calories to your diet.
Correct answer: A
Rationale: The correct answer is A: 'Wear sunglasses when outdoors.' To minimize the anticholinergic effect of Clomipramine, the client should wear sunglasses when outdoors to reduce photophobia. This adverse effect is common with tricyclic antidepressant (TCA) use. Choices B, C, and D are incorrect. Checking temperature daily, timing of medication intake, or adding extra calories to the diet are not directly related to minimizing adverse effects of Clomipramine.
4. In an acute mental health facility, a patient experiencing opioid withdrawal has a new prescription for Clonidine. What action should the nurse identify as the priority?
- A. Administer the Clonidine as prescribed.
- B. Provide ice chips to the patient.
- C. Educate the patient on Clonidine's effects.
- D. Obtain baseline vital signs.
Correct answer: D
Rationale: In this scenario, the priority action for the nurse is to obtain baseline vital signs. This is essential for establishing a baseline assessment, especially for a patient undergoing opioid withdrawal and starting a new medication like Clonidine. Monitoring vital signs is crucial for evaluating the patient's response to treatment and detecting any potential complications early on. Administering the medication, providing ice chips, and educating the patient on Clonidine's effects are important tasks but obtaining baseline vital signs takes precedence to ensure the patient's safety and proper management.
5. A client has a new prescription for Losartan. Which of the following laboratory values should the nurse monitor?
- A. Serum potassium
- B. Serum sodium
- C. Serum calcium
- D. Serum magnesium
Correct answer: A
Rationale: Corrected Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. Monitoring serum potassium levels is crucial to detect and manage any potential hyperkalemia, which can lead to serious cardiac arrhythmias. Monitoring serum sodium, calcium, or magnesium levels is not typically required when a patient is on Losartan unless there are specific indications or comorbidities that warrant such monitoring.
